But as the dog sniffs her way toward record cocaine interdictions, she has also become the latest target of Colombia’s most powerful drug gang.

Colombian police recently revealed that the Gulf Clan, a cartel that boasts its own guerrilla army, has offered a reward of $7,000 to whoever kills or captures the savvy hound.

The threat prompted officials to relocate Sombra — whose name in Spanish means Shadow — from a busy port on Colombia’s Caribbean coast to the capital city, where she now uses her extraordinary talent to sniff through suspicious cargo at Bogota’s El Dorado International Airport.

After her six hour shift is over, Sombra is transported in a van with tinted windows back to her kennel. She is usually accompanied by two armed guards.

“We are responsible for her safety,” said officer Jose Rojas, Sombra’s 25-year-old handler.

Sombra’s detective work is needed now more than ever as Colombia wrestles with soaring coca production that is testing traditionally close relations with the United States. A recent White House report found the amount of land where peasants and drug traffickers harvest the plant used to make cocaine rose 11 percent in 2017 to 209,000 hectares (516,450 acres), despite $10 billion in U.S. counter-narcotics work.
